SHEET-METAL PAN.

SPECIFICATION forming part of Letters Patent No. 224,396, dated FebruaryI0, 1880.

- Application filed October 20, 1879.

' in the county of Suffolk and State of Massachusetts, have invented anew and Improved Sheet-Metal Pan, of which the following is aspecification. V

Figure 1 is a p1an view,representinga sheet of metal cut in proper shapefor the construction of the pan. Fig. 2 is a longitudinal sectionalview, representing the second step in the construction of the pan,wherein the edges of the plate are once folded over and the ring is putin position. Fig. 3 is alongitudinalsectional view, representing thethird step in the constructiomwherein the edges of the plate are stillfurther folded over. Fig. 4 is a 10ngitudinal sectional elevation of acompleted pan. Fig. 5 is a plan of the ring and its ear; Fig. 6 is anend elevation of the pan.

The invention consists in a sheet-metal pan with flat bottom, flatfoldededges, a ring, and an ear. as hereinafter described.

In the drawings, Ai-epresents the octagonal blank or sheet of metal.(Shown flatin Fig. 1.) In Fig. 2 the edges or. of the sheetAare shownfolded over upon the surface of the said sheet, and the ring B is shownattachedto the said sheet A by means of the insertion of the ear b undera fold, a. In Fig. 3 it is shown that another bend, c, in made in theedge of the com.- pleted part.

In Fig. 4 the completed pan is represented, in which A is the bottom; 0,the sides; a, the folded edge; 0, the inner bend of the edge; B, thering, and b the ear holding the said ring B to the pan. Itis found thatthis folded edge e is stiffer than the ordinary wired pan-edges are, andis much cheaper of construction; and it is also found that the ring B issecurely held to the pan by the binding or folding of the ear I) in thefolded edge 0.

In Fig. 6 the corners g are shown. impart strength and stiffness to thepan.

The corners are first cut from the sheet of metal to form the blank A;next the edges of the blanks are folded over, and the ear I), with ringB, is inserted under one of the folds thirdly, the folded edges areturned up at right angles to the body of the blank, so as to bend theear b in the fold; fourthly, the sheet is reversed and struck up with a(lie into the form shown in Fig. 4 of the drawings; lastly, the cornersg are folded down, as shown in Fig. 6.

This pan then, thus constructed without rivets, wire, or solder, andhaving its ring secured to it without the use of rivet or solder, has

They

edges as strong and as durable as the ordinary wire-edged pan, is ofsomewhat less weight, is

more convenient in use, because its broad flat edges afford a good holdin putting it in or out of an oven, and can be manufactured at a greatlyreduced cost of material, time, and labor. V Having thus fully describedmy invention, I claim as new and desire to secure by Letters Pateut-- Asan improved article of manufacture, the sheet-metal pan hereindescribed, having a flat bottom, flat folded edges a, folded corners g,and ring and ear B b, substantially as set forth.
